Celtic striker has haunted Rangers regularly.
The French striker though could yet have a parting gift for Celtic - another demolition of rivals Rangers.
Dembele's fan favourite status at Celtic was secured in an instant back in September 2016 when he scored a fantastic hat-trick to down Rangers.
Dembele's treble in the 5-1 win was part of a show of power from Celtic from which Rangers never recovered.
He scored against Rangers again in a 2-1 win last season, as well as netting a winner in a 1-0 Scottish League Cup win.
Even this season when he was just returning from injury, Dembele provided an assist in Celtic's 2-0 win at Ibrox.
He has five goals against the Gers, a figure he is yet to top against any other team in his career to date.
Celtic selling Dembele will be seen as a big positive by Rangers no matter how they replace him, thanks to his fantastic record against them.
But it is not too late for him to prove a scourge of Rangers one last time, with the two teams facing off this weekend.
Dembele has been rotated in and out of the side by Brendan Rodgers recently, perhaps with the manager having an eye on the team after his potential departure.
This weekend he must quite simply play his best striker, Dembele, and give the Frenchman the perfect send off by allowing him to demolish their rivals one more time.
